About Cosine
What is Cosine
Cosine is an AI coding tool designed for production software teams. It is built around Lumen, a model trained exclusively on real production code from real engineering teams. Unlike general-purpose AI models, Lumen focuses on one task: writing exceptional software. It is optimized for maintainability, readability, and production-quality outputs, avoiding bloated code generation. Cosine can be used in a terminal-native interface or in a cloud-based collaborative environment, and it supports deployment in various security environments including public cloud, managed single-tenant cloud, and fully air-gapped setups.
Key features
Lumen is trained on real production code, making it a specialist in software development. It is optimized for maintainability and readability, reducing 'AI slop' in generated code. It can reason across complex architectures, legacy infrastructure, and long-lived codebases. It supports enterprise and niche languages including COBOL, Fortran, Verilog, Rust, and complex SQL. Cosine offers a terminal-native interface with local-to-remote execution, external tool access via MCP, and multi-agent orchestration. The cloud version allows parallel coding tasks and collaboration across engineers, PMs, and stakeholders. Deployment options include public cloud, managed single-tenant cloud, and fully air-gapped environments.
Use cases
Cosine is suitable for production software teams that need to ship better code faster. It can be used in terminal-based workflows for developers who prefer command-line tools. The cloud environment supports planning large changes and collaborating across team members. It is designed for complex systems, legacy infrastructure, and niche programming languages, making it useful for enterprises with specialized codebases. The model family includes Scout for on-device, cheap operations, Outpost for everyday production tasks, and Frontier for the hardest engineering problems (coming soon).
